“…Acid‐promoted decomposition of aryltriazenes dissolved in aqueous media typically involves general acid catalysis (A‐S E 2) 10 or specific acid catalysis (A1) 8,11. Decomposition of 1 , under experimental conditions analogous to those of this study, has been found to follow an A1 mechanism (Scheme ), as rates increase with decreasing pH and are independent of the buffer concentration 12.…”

Acid-promoted N N bond cleavage in 1,3-diphenyltriazenes (X-Ph-N=N-NH-Ph-X; X = H, 4-OCH 3 ), leading to formation of diazonium ions and anilines, is strongly inhibited in aqueous solutions in the presence of cyclodextrins (CDs). The inhibition is ascribed to the formation of inclusion complexes that render the guest diphenyltriazene significantly less basic as a result of the less polar nature of the CD cavity (a microsolvent effect). Association equilibrium constants for 1:1 host-guest complexes increase in the order α-CD <β-CD ∼ permethyl-β-CD < hydroxypropyl-β-CD, with values for X = 4-OCH 3 being larger than those for X = H. In the case of α-CD, formation of 2:1 host-guest complexes is also involved. C

5-Nitro-2,1-benzothiazole-3-diazonium ion reacts with various substrates (phenol, 2-naphthol, mesitylene, acetone, acetylacetone, ethyl acetoacetate) to give corresponding azo or hydrazo compounds. Characterization of the prepared compounds by means of multinuclear magnetic resonance, X-ray diffraction, and HRMS together with the study of acidobasic properties is presented, as well as significant solvatochromism.
